Description
The Honeywell Modutrol IV Motor M9494D1000 is a spring-return motor designed for reliable operation of dampers or valves in HVAC applications. Suitable for both line- and low-voltage control, this motor ensures that the controlled element returns to its starting position during power failures or interruptions. The M9494D1000 operates as a proportional reversing actuator with a 135 Ohm input signal and is powered by a 24 Volt AC supply. It features adjustable timing from 60 to 120 seconds and a stroke range of 90 to 160 degrees. With a torque output of 300 Lb-In and a normally closed electric position, it does not include auxiliary switches. Compatibility with resistor kits, resistor boards, or interface modules allows this motor to be driven by controllers providing current or voltage electronic signals, making it versatile for various control scenarios. This robust motor is ideal for ensuring dependable and precise control in demanding applications.
Features
- Integral junction box provides NEMA 3 weather protection.
- IIntegral spring return returns motor to normal position when power is interrupted.
- IMotor and circuitry operate from 24 Vac. Models available with factory installed transformer, or a field added internal transformer.
- IQuick-connect terminals are standard—screw terminal adapter is available.
- IAdapter bracket for matching shaft height of older motors is available.
- IMotors have field adjustable stroke (90° to 160°).
- IDie-cast aluminum housing.
- IIntegral auxiliary switches are available factory mounted, or can be field added.
- INominal timing standard of 30 seconds (90° stroke), and 60 seconds (160° stroke). Other timings available.
- ISpring return motors can operate valve linkages form power end or auxiliary end shafts for normally closed or normally open valve applications.
- IAll models have dual shafts (slotted and tapped on both ends).
- IAll models have auxiliary switch cams.
- IFixed torque throughout the entire voltage range.
- IMotors are designed for either normally open or normally closed valves and dampers.
- IField addable interface modules can be mounted in the junction box to upgrade the motor to Series 70 (electronic) control.
